In that case:
% :
cd $(MASTERDIR) && \
pwd=`$(MASTERDIR)/relative-pwd` &&
$(MAKE) RUNDIR="$${pwd?}" $@
Where $(MASTERDIR)/relative-pwd is this script:
#!/bin/sh
topdir=`dirname "$0"` &&
topdir=`(cd "${topdir?}" && pwd -P)` &&
subdir=`pwd -P` &&
case ${subdir?}/ in
"${topdir?}"/*)
length=`wc -c <<EOT
${topdir?}
EOT
` &&
length=`expr ${length?} + 1` &&
cut -c "${length?}"- <<EOT
${subdir?}
EOT

*)
echo "Sorry, you're outside my jurisdiction." >&2 &&
exit 1;;
esac
